`fixBigInt` transforms some `GET` request `res.body`s to string.

In fact, few services that utilize the fixBigInt parse the returned string back to object. https://github.com/nowcommunity/nowdatabase/blob/64fe98f7488bc7e084d235d3c7fc7ffa354a3fb1/backend/src/services/species.ts#L70

Also this transformation is made for only some paths: https://github.com/nowcommunity/nowdatabase/blob/64fe98f7488bc7e084d235d3c7fc7ffa354a3fb1/backend/src/routes/species.ts#L13 but not https://github.com/nowcommunity/nowdatabase/blob/64fe98f7488bc7e084d235d3c7fc7ffa354a3fb1/backend/src/routes/species.ts#L20

Indeed, best to do it in one level, I probably meant to refactor it into services but forgot some of it.
